-----------------------------------
Summary: Tile generation fails for slices with single lats or lons
Key: SDAP-502
URL: https://issues.apache.org/jira/browse/SDAP-502
Project: Apache Science Data Analytics Platform
Issue Type: Bug
Components: granule-ingester
Reporter: Riley Kuttruff
Assignee: Riley Kuttruff
Data subsetting in the tile reading processor uses np.squeeze on subsetted data
([example|[https://github.com/apache/incubator-sdap-ingester/blob/0589f473c66a68830aca4b06160f8e756459e4f6/granule_ingester/granule_ingester/processors/reading_processors/GridReadingProcessor.py#L35-L42]).]
In the event that a tile is one greater than a multiple of the desired tile
size (eg, dim length mod dim tile length == 1), we will get a lat or lon subset
whose dimension lengths are all 1. When that is squeezed, the result is a
0-dimension numpy array, which can then throw an error, say, it it is used as
an input to len().
A simple fix would be to check if the squeezed subset is 0-dimensional and then
expanding it into a dimensioned array.
